活性炭粉对硝基苯水相洗消性能实验研究

Experimental study on the effect of activated carbon powder on the removal of nitrobenzene in aqueous phase

选取活性炭粉作为洗消剂,以硝基苯为洗消吸附对象,对其水相泄漏进行小型实验模拟。利用恒温水浴振荡加热、紫外光谱、控制变量等方法,精确得到活性炭粉对硝基苯的水相洗消量,并结合洗消动力学、洗消等温机理等理论模型计算出相应方程,对其洗消机理和影响因素进行深入研究。得出活性炭粉对硝基苯的水相洗消不仅仅是物理吸附过程,还受内部化学分配以及电子间相互作用的影响的结论。

Activated carbon powder was selected as the detergent and nitrobenzene was used as the adsorption object to simulate the water phase leakage.By means of constant temperature water bath oscillation heating,UV spectrum,control variables and other methods,the amount of nitrobenzene washed by activated carbon powder in water phase is accurately obtained,and the corresponding equations are calculated by combining the theoretical models of washing kinetics and washing isothermal mechanism,and the washing mechanism and influencing factors are deeply studied.It is concluded that the removal of nitrobenzene by activated carbon powder is not only a physical adsorption process,but also influenced by internal chemical distribution and electronic interaction.
